Answer 1

$2 \frac{1}{3} + 4 \frac{1}{10} \div (2 \frac{7}{15} - \frac{5}{12} ) \times \frac{5}{6} = \frac{7}{3} + \frac{41}{10} \div ( \frac{37}{15} - \frac{5}{12} ) \times \frac{5}{6} = \frac{7}{3} + \frac{41}{10} \div \frac{41}{20} \times \frac{5}{6} = \frac{7}{3} + \frac{41}{10} \times \frac{21}{40} \times \frac{5}{6} = \frac{7}{3} + 2 \times \frac{5}{6} = \frac{7}{3} + \frac{5}{3} = 4$

$4)4 \frac{5}{12} - 1 \frac{1}{2} \div (2 \frac{1}{6} + \frac{8}{15} ) \times 1 \frac{4}{5} = \frac{53}{12} - \frac{3}{2} \div ( \frac{13}{6} + \frac{8}{15} ) \times \frac{4}{5} = \frac{53}{12} - \frac{3}{2} \div \frac{27}{10} \times \frac{4}{5} = \frac{53}{12} - \frac{5}{9} \times \frac{4}{5} = \frac{53}{12} - \frac{1}{9} \times 4 = \frac{53}{12} - \frac{4}{9} = \frac{143}{36} = 3 \frac{35}{36}$
